Abstract

Salah satu bidang ilmu yang mempunyai orientasi pada wirausaha dan industri kecil (home industry) bagi masyarakat usaha adalah teknik pelapisan logam dekoratif atau disebut pernekel. Proses pelapisan logam dekoratif dengan menggunakan arus listrik searah atau yang lebih dikenal di lingkungan masyarakat dengan istilah elektroplating mempunyai peranan penting dalam industri baik industri yang berskala besar maupun industri yang berskala kecil. Kegiatan ini bertujuan untuk meningkatkan minat wirausaha teknik pelapisan pada masyarakat di perkotaan melalui model simulasi wirausaha dengan jumlah peserta 15 orang. Kegiatan dimulai dari penyusunan instrumen, pelaksanaan pre-test minat wirausaha, dilanjutkan dengan pemberian materi pelatihan dan simulasi wirausaha, dan diakhiri dengan pelaksanaan post-test. Materi instrumen mencakup semua indikator minat dan motivasi wirausaha. Jumlah pertanyaan masing-masing sebanyak 34 dan 36 butir soal. Teknik analisis data menggunakan teknik deskriptif kuantitatif. Hasil pre-test terhadap para peserta pelatihan adalah 62,8. Kemudian hasil post-test terhadap para peserta adalah 112,86. Hasil ini membuktikan bahwa model simulasi wirausaha yang diterapkan melalui pelatihan dapat meningkatkan minat wirausaha.

Abstract

Team-Based Project (TBP) learning has gained prominence in engineering education as a means to develop both technical competencies and professional skills through collaborative engagement. Despite extensive documentation of TBP outcomes, limited research has explored the qualitatively different ways in which students understand and experience TBP, particularly within the distinct context of mechanical engineering education programs that integrate technical and pedagogical preparation. This study employs a phenomenographic research design to investigate mechanical engineering education students' qualitatively different ways of experiencing TBP. Data were collected through semi-structured interviews with 63 students at various academic stages across two universities in Indonesia. Analysis followed phenomenographic principles, identifying categories of description that capture qualitative variation in students' understanding, rather than reporting frequency distributions. Findings reveal four qualitatively distinct categories of description: (1) TBP as task completion, (2) TBP as collaborative skill-building, (3) TBP as professional preparation, and (4) TBP as transformative learning. These categories form an outcome space in which more sophisticated conceptions encompass awareness of collaborative processes, professional relevance, and critical reflection. Persistent structural challenges particularly inequitable workload distribution and coordination difficulties feature differently across categories. The study contributes context-specific insights into how TBP is understood in a technically and pedagogically hybrid engineering program, with implications for curriculum design, team formation, and instructor support strategies.

Abstract

This study investigates the corrosion resistance, surface hardness, morphological structure, and predicted lifetime of carbon steel coated with pure zinc (Zn) and zinc aluminum alloy (ZnAl) in chloride rich environments. Coatings were applied by hot dip galvanizing, and characterized using Field Emission Scanning Electron Microscopy Energy Dispersive X-ray Spectroscopy (FESEM-EDS), Vickers hardness testing, and salt spray testing. Before exposure, both coatings confirmed homogeneity with smooth, topographically uniform surfaces, and no macroscopic defects. ZnAl coatings also delivered superior hardness compared to pure Zn and uncoated steel. After exposure, ZnAl maintained smoother, more stable surfaces with smaller and fewer pitting defects, whereas pure Zn suffered medium to severe damage. Pure Zn coatings showed fluctuating corrosion behavior with an average rate of 7.8944 µm/year, while ZnAl coatings exhibited minimal fluctuations within ±0.1 µm/year, indicating high resistance to chloride concentration. Predicted lifetime ranged from 3.7 to 5.5 years for pure Zn (average 4.7 years) and 5.9 to 6.5 years for ZnAl (average 6.2 years). Despite being thinner, ZnAl provided superior corrosion protection and structural stability. These findings indicate that ZnAl alloy coatings provide superior corrosion protection, structural stability, and mechanical performance for carbon steel in chloride rich environments.
